Will attempt to load profiles automatically. If loading fails but the profiles are already loaded, execution will continue. A hard failure will only occur if Docker cannot load the profiles *and* they have not already been loaded via some other means. Also introduces documentation for AppArmor.

AppArmor security profiles for Docker
|
|
--------------------------------------
|
|
|
|
AppArmor (Application Armor) is a security module that allows a system
|
|
administrator to associate a security profile with each program. Docker
|
|
expects to find an AppArmor policy loaded and enforced.
|
|
|
|
Container profiles are loaded automatically by Docker. A profile
|
|
for the Docker Engine itself also exists and is installed
|
|
with the official *.deb* packages. Advanced users and package
|
|
managers may find the profile for */usr/bin/docker* underneath
|
|
[contrib/apparmor](https://github.com/docker/docker/tree/master/contrib/apparmor)
|
|
in the Docker Engine source repository.
|
|
|
|
|
|
Understand the policies
|
|
------------------------
|
|
|
|
The `docker-default` profile the default for running
|
|
containers. It is moderately protective while
|
|
providing wide application compatability.
|
|
|
|
The `docker-unconfined` profile is intended for
|
|
privileged applications and is the default when runing
|
|
a container with the *--privileged* flag.
|
|
|
|
The system's standard `unconfined` profile inherits all
|
|
system-wide policies, applying path-based policies
|
|
intended for the host system inside of containers.
|
|
This was the default for privileged containers
|
|
prior to Docker 1.8.
|
|
|
|
|
|
Overriding the profile for a container
|
|
---------------------------------------
|
|
|
|
Users may override the AppArmor profile using the
|
|
`security-opt` option (per-container).
|
|
|
|
For example, the following explicitly specifies the default policy:
|
|
|
|
```
|
|
$ docker run --rm -it --security-opt apparmor:docker-default hello-world
|
|
```
